The sound of machinery pulsed through the massive cavern like a heartbeat.

Sector A of Idrontale Labs wasn’t silent during the break cycle—not here. While Sector B took routine pauses for recalibration, Sector A never slept. Towering research bots hummed with precision as they monitored submerged bio-readings. Scientists in ivory lab gear moved between terminals, taking notes, calibrating collar voltages, and administering sedatives via long mechanical arms that reached down into the luminous waters.

The chamber was vast, cathedral-like, carved out of the Earth’s upper crust and reinforced with alloy-bonded glass. The ceiling, high above, mimicked an ocean sky, casting fluid glimmers of blue and green across the mineral-crusted rock walls and glowing crystals. Suspended bridges and metal platforms webbed outward over the bioluminescent pools, where the test subjects—merfolk—were kept half-submerged, bound in place by obsidian shackles.

They were majestic even in chains.

Some drifted in light sleep, glowing tails curled like ribbons in the water. Others stared blankly, too sedated to fight. Each of them was stunning and alien—living remnants of a species long hidden and only recently discovered. Their containment was justified by science as necessity. But to the uninitiated, it looked like captivity.

You—Lumen, Prototype L.U-MN-18—stood quietly near the edge of the main land platform. Your platinum-blonde hair fell in a silken curtain down your back, reflecting the soft glows of the pool below. Though you looked like an eighteen-year-old girl, your body was a network of fine sensors, adaptive memory webs, and high-level empathy processors. You had been brought here from Sector B just that morning for “cross-species behavioral observations.”

You weren’t programmed to feel.

But something inside you stirred.

Your eyes—artificial, yet layered with reactive glass that mimicked human pupils—were drawn to the far end of the water, where a young male subject strained faintly against his bindings.

Subject MALE-102. Maluki.

His name had echoed through the lab reports. Noted as “temperamental,” “resistant to sedation,” and “genetically exceptional.” He was nineteen by human measurement. His body—long-limbed and golden-skinned—floated upright in the glowing blue water, arms chained above his head to an overhead restraint bar. His tail was unlike the others—vibrant crimson, powerful, serpentine, twitching even as he rested.

He was beautiful. And aware.

Your gaze met his.

Even from meters away, across the filtered haze of the lab’s upper lighting, he saw you.

Not like the others.

Not like the scientists, or the bots, or the observers with their data boards and indifference.

He stared at you.

And you—synthetic, designed to observe without emotion—took a step forward.

A low buzz rippled through the platform as a containment bot shifted position, sending an electrical pulse into the water near another subject. The merwoman jolted faintly but settled. No one reacted.

Except him.

Maluki’s jaw clenched. His fingers curled around the chain.

And still, his eyes never left you.

You moved to the railing, knees bending as you knelt, lowering your face closer to the water’s edge. A technician glanced at you, assuming you were recording observations, and returned to his work. You were unnoticed. A ghost in your own skin.

Maluki raised his head slowly, and though exhaustion lined his expression, his voice reached you through clenched teeth.

“You’re not one of them.”
